Describe the Bug

I created a custom 404 page (following the docs: https://docs.astro.build/en/core-concepts/astro-pages/#custom-404-error-page).

But when hitting this page, the status code of the document is still 200 OK!?
404 Not Found is expected.

(Use the web inspector to see this.)

Note that the logs of Astro ARE logging 404 though. Is the status code of the page even set by Astro?

What's the expected result?

Status code 404

Perhaps any updates on this topic? For SEO reasons, this is quite an annoying bug that I haven't been able to find an easy solution for...

Will look into it

@xriter , The 200 status code is returned only in development, but I can see the 404 status code when building with the node adapter. Is your issue related only to the development mode?

[xriter]

@ematipico You are right. It appears to be correct in the production mode. Only in development mode it gives the unexpected 200 OK. Is this deliberate? Or should it also just give 404 Not Found in development mode?

[ematipico]

Yeah it's a bug, we'll have to look into it.

Taking a look at this one now! Once #7693 is merged it should be a straightforward fix.

Hi, the issue is still here.
If I go to the 404 page directly it returns a 200 status, like the page exists and route too.

In Dev mode, it returns a 404, but after the build it's 200.
